Groundwater data was collected and compiled from published literature to evaluate the source and flow paths of groundwater. Stable isotopic ratios of hydrogen and oxygen in water were used to evaluate the seasonal precipitation source of groundwater recharge. The mixing model is described in Solder and Beisner (2020), which estimates mixing end-members from precipitation and surface water data. The final calculated value is the fraction of recharge from winter precipitation as reported here.
